However, I have heard that battery life between charges can be improved doing as you suggest. I gather that it involves "rooting" the phone - is that correct? Unfortunately I also heard that doing so voids the warranty. Maybe I'll try it after the warranty runs out.
Yes it requires the phone to be rooted and yes that voids the warranty. Apparently the phone can be unrooted, in case you need to send it back. There may be some faults which would prevent you from unrooting it but you may wish to consider the likelihood. I rooted mine straight away and don't regret it. It would be a shame to go without this functionality for a year but it's up to each owner to decide. Good luck, either way.
